Since we still are obligated to use ball ammo, then .45acp is the only choice. Proper training, if anyone is still capable of giving it, makes a 1911 the only choice.
I can understand the idea of the D.A. so that panicky people can pull out a gun and shoot. Not my idea of proper ttraining or tactics. The same person can grab the pistol wrong (after all, the training has been minimal) and AD, scratch that, negligent discharge. Simple, proper training will make a 1911 fine. It's a paperweight unless you cock it, or unless you flip off the safety if it already is cocked, and hold it correctly. I do not see it as a problem. I think the only issue one might have with 1911 design is possible maintenance issues with the grip safety, especially in sand. But, that was also part of the initial test regime for acceptance, so the odds of a problem are minimal.
